Here, recently exposed brine, or salty liquids, in the center of the crater were pushed up from a deep reservoir below Ceres' crust. In this view, they appear reddish. Seen here is Cerealia Facula ("facula" means bright area), a 9-mile-wide (15-kilometer-wide) region with a composition dominated by salts. The central dome, Cerealia Tholus, is about 1.9 miles (3 kilometers) across at its base and 1,100 feet (340 meters) tall. The dome is inside a central depression about 3,000 feet (900 meters) deep.
